Signing Martin for 20 million? Comparing data from Onana and Martin, there is actually little difference in data

Some fans asked Onana and Martinez about data comparison, which would naturally be satisfied. This should be based on the recent news that Manchester United wanted to sign Martinez and Aston Villa wanted to sell for £20 million. There were rumors about this just after the season ended.

Martin has a long contract with Villa, and it is Villa's main goalkeeper who has won the top six of the Premier League. At this time, it is rumored that Villa will change the goalkeeper, provided that Villa can find a good goalkeeper, and Martinez is willing to have no European game next season, so this deal can only be formed. As for data comparison, data is not useless. It is just the background of the data occurrence and the interpretation of the data that lead to different impressions. Data is the most basic and objective. Let’s take a look at the basic data first.

Comparison of basic data: Martin's activity range is larger

The following figure should be the comparison of basic data that fans can find, and the data source is Sofa. Under Sofa score, Martin's score is obviously higher, but it is not much higher. Sofa scores are purely based on data performance. It has its own set of core calculation methods, with a basic score of 6.5 points, which are added and subtracted according to the weights of each data.

Onana's score is higher than 6.5 points, not lower than the Premier League average. Considering that Villa, where Martinez is located, wins more games and scores, from the perspective of Sofa, some fans actually say that Martinez's performance may not be better, but there is a certain reason.

Activity range: Martinez is better

There are several key indicators for evaluating the activity range, one of which is the average defense line distance, which is the distance from the goal by himself. The goalkeeper position has already superimposed too much content on the basis of saves. Once the team pushes up, the goalkeeper will even rush out of the penalty area to assume part of the defender function.

The above picture can clearly see the differences in Onana and Martinez's combat data and range of activities. The team's style is different. Onana faces fewer crosses, but from the average, Martinez's control over crosses is indeed better than Onana. Compared with the impression of the game, Manchester United lost a lot of corner kicks this season. Overall, Martinez is also better than Onana in terms of range of activities.

Save efficiency: The difference between the two sides is not big

Football team evaluates the goalkeeper's saves. In fact, there is a key data called PSXG. The reason for introducing this data is that some teams have weak defenses and have many shots by their opponents, but most of them are long shots outside the penalty area. This number of saves made is of little significance. So in a sense, PSXG measures the difficulty of each save.

switched to the average data of 90 minutes. Onana and Martin's PSXG are actually 1.29. Onana has made many divine saves this season, but they have been covered up by many mistakes. Martinez also made many mistakes this season, but they have been covered up by the divine saves. This is the data in the background of Onana's average of 0.03 own goals per game.

The above figure should be a more intuitive data comparison. Onana faces more shots, but Onana conceded slightly less goals than Martinez. Villa conceded 51 goals this season and Manchester United conceded 54 goals this season, but Onana played three fewer Premier League games than Martinez.

Passing ability: Onana makes more mistakes

Onana was introduced as an outgoing goalkeeper, but after taking Onana, Manchester United's overall formation shrinks, and it is incomprehensible to use an outgoing goalkeeper as a goal line-type goalkeeper. The following picture shows the comparison between Onana and Martinez in terms of passing data.

Onana almost directly assisted several times this season. When he played for Inter Milan, he was famous for directly contacting the forwards. Therefore, in terms of passes and shots this season, Onana is better than Martinez. However, Onana also passes the ball to the opponent a lot of times; and Martin passes the ball directly out of bounds, there are more data. Overall, Onana made more mistakes, while Martin was relatively stable in passing.

This is also related to the situation of Manchester United this season. Manchester United's defense line often seems panicked, rather than being calm and confident in passing and controlling the ball.

Summary: The gap in self-confidence

Overall, Villa is a team in the Europa League this season, while Manchester United is just a team in the middle and lower reaches, just looking at the rankings. The gap reflected in the data of the two is actually a matter of stability. The save efficiency of both sides is actually similar, but Onana's psychological quality and game performance are more unstable, while Martin is more stable.

When Manchester United won the worst ranking in the Premier League era, it is difficult to evaluate a player's performance well. It is normal to perform poorly, but this team of Manchester United is not that bad. Their instability and large psychological fluctuations are the core issues. If this problem is not solved, the team's mistakes will spread like a plague.
